Pomerantz LLP launched an investigation into NuScale Power Corporation on September 24, 2026. The firm is investigating potential securities fraud and unlawful business practices.

Investigators are examining whether leadership made misleading statements or withheld material information. This probe follows a significant UBS analyst downgrade on September 11.

UBS cited a loss of competitive edge and lengthy build timelines as primary concerns. The analyst also noted a lack of firm customer orders for the company.

NuScale's stock price fell 15.67% on the day of the UBS announcement. The formal investigation adds further selling pressure as investors weigh legal and financial risks.
